Perform a cold start after the vehicle has sat for hours and listen for any rattle or ticking from the right side of the engine. | Note: Although the Euro 6 EP6FDT engine features an updated timing chain design compared to the older EP6CDT, tensioner fatigue and chain stretch can still occur.
Accelerate hard in Sport mode from low RPMs up into higher gear ranges and monitor for power surges or hesitation. | Note: High-Pressure Fuel Pump (HPFP) failures remain an issue on these Euro 6 versions, though less frequent than early models. Look for stuttering under heavy load.
Check the plastic coolant expansion tank and the thermostat housing area for white or pink crystalline crusting. | Note: The plastic thermostat housings are highly prone to hairline fractures, leading to slow coolant loss that can cause severe overheating if unnoticed.
Test the upgraded SMEG+ touch screen infotainment system for responsiveness, Bluetooth pairing, and reversing camera lag. | Note: The SMEG+ systems can experience slow response times, internal software freezing, or total screen blackout, often fixed only by firmware updates or module replacement.
Routine service utilizing specific low-viscosity PSA B71 2312 (0W-30) synthetic oil to prevent low-speed pre-ignition (LSPI) and protect the turbo.
Mandatory spark plug replacement using high-grade iridium plugs; check for oil misting around the valve cover gasket and turbo lines.
Major service milestone. Complete inspection of the timing chain slack, replacement of the accessory drive belt, and preventative coolant flush.
Strictly utilize engine oils meeting PSA B71 2312 specification; using incorrect oil grades will quickly ruin the anti-friction coatings.
Clean the intake valves via professional carbon cleaning methods every 60,000km to treat direct-injection carbon crusting.
Inspect the front and rear brake pads; Phase 2 models have soft factory brake rotors that wear out quickly alongside the pads.
Verify the integrity of the scuttle drain flaps under the wipers to ensure rain water doesn't pool and leak into the primary fuse box.
Test battery health; Phase 2 cars with advanced Stop/Start systems require heavy-duty EFB/AGM batteries to avoid false electronic errors.
Estimated repair costs if issues arise
Still a known vulnerability on the updated Prince engine family; symptoms include long engine cranking or limp mode under load.
Preventative replacement is required if a cold start rattle becomes audible; includes guides, upgraded tensioner, and seals.
Required when the integrated plastic housing cracks and leaks fluid; involves replacing the full housing assembly and electronic sensor.
